L.A. has the most polluted air in the U.S. despite a 6% improvement in 2021, report says
No matter how effective we become in reducing carbon emissions, there remains the need to remove carbon from the atmosphere in order to reverse the effects of climate change. UCLA researchers may have the answer.
"The country's reliance on fossil fuels, increasing severity of wildfires as well as varying enforcement of the Clean Air Act from administration to administration have all added to U.S. air pollution,'' according to the report."Nationwide, 264 million people lived in areas where pollution levels were above the WHO annual guideline for PM2.5 concentrations in 2021.''
The report found that worldwide, only 222 cities of the 6,475 analyzed met the WHO standards for fine-particle pollution. The French territory of New Caledonia, and the U.S. territories of Puerto Rico and the Virgin Islands met the guidelines. "We understand better than ever before how air pollution damages our health and economies,'' Greenpeace India Campaign manager Avinash Chanchal said in a statement released with the report.
"This report is a wakeup call, revealing how people worldwide are denied access to clean air," Chanchal said."Particulate matter air pollution is produced through burning fuels including coal, oil and fossil gas, unsustainable development, and agricultural activities. Addressing the air pollution crisis requires the development of renewable energy resources and clean-powered, accessible public transport.
